Extract files with the same names in subfolders and save them into a new folder with a different name

30 visualizaciones (últimos 30 días)
I have .png files with the same name stored in different folders. My goal is to rename and copy them into a new folder. The following code just saves the last image in the new folder. I am not able to figure out how to save PNG files with incremental values in name. I would appreciate any help. Thanks in advance.
myFolder = 'current folder path';
filePattern = fullfile(myFolder, '**/*.png');
theFiles = dir(filePattern);
numFiles = length(theFiles);
outputFolder = 'new folder path';
for K = 1 : numFiles
baseFileName = theFiles(K).name;
fullFileName = fullfile(theFiles(K).folder,baseFileName);
limages = imread(fullFileName);
fullFileName = fullfile(outputFolder, theFiles(K).name);
imwrite(limages,fullFileName);
end

Is there any character that is valid in file names, that we are permitted to assume does not occur in the file names in question? For example are we permitted to assume that the original filenames will never end with underscore and then a number just before the extension?
When the files get renamed as they are copied into the new directory, is it necessary to identify which directory each version came from? For example cracked/20220311.png -> 20220311_cracked.png ?

@Walter Roberson Thank you for your response. There are no such requirements. I just want to retrieve and store all the files in a single folder. A number before the file extension with underscore is also fine. My files in subfolders are named as output_img.png.

%%
myFolder = 'current folder path';
filePattern = fullfile(myFolder,'**','*.png');
theFiles = dir(filePattern);
numFiles = length(theFiles);
outputFolder = 'new folder path';
mkdir( outputFolder )
for K = 1 : numFiles
source_file = fullfile( theFiles(K).folder, theFiles(K).name );
target_name = sprintf( '%s_%03d.png', theFiles(K).name, K ); % less than 999 files
target_file = fullfile( outputFolder, target_name );
copyfile( source_file, target_file );
end
And some error handling and testing.

Instead of this:
source_file = fullfile( theFiles(K).folder, theFiles(K).name );
target_name = sprintf( '%s_%03d.png', theFiles(K).name, K ); % less than 999 files
try this
% Create source full file name.
baseFileName = theFiles(K).name;
inputFolder = theFiles(K).folder;
sourceFullFileName = fullfile(inputFolder, baseFileName);
% Create full destination file name.
[~, baseFileNameNoExt, ext] = fileparts(baseFileName);
targetBaseFileName = sprintf('%s_%03d.png', baseFileNameNoExt, K); % less than 999 files
targetFullFileName = fullfile(outputfolder, targetbaseFileName);
% Copy the source file, with it's new name, to the destination folder.
copyfile(sourceFullFileName, targetFullFileName);
